Abstract
Provided are an oil degradation meter and a method for evaluating oil degradation, which allow a user to set an arbitrary level of degradation of an oil/fat using acidic value (AV) as an indicator, regardless of differing parameters such as the moisture content of foods to be fried, so as to allow the user to know, easily and with reliable repeatability, when to change the oil/fat. According to a setting procedure, the user: sets the acidity value (AV0) of unused oil/fat as 0; measures and records the dielectric constant (D0) of the oil/fat at this time; measures the dielectric constant (D100) of the oil/fat at the time of changing under specific oil/fat usage conditions; and records this dielectric constant (D100) along with the acidity value (AV100) at this time. According to a measurement procedure, the user measures the dielectric constant (Dn) of a sample oil/fat, and calculates the acidity value (AVn) of said sample oil/fat on the basis of the dielectric constants (D0, D100) and the acidity value (AV100) recorded during the setting procedure, using the formula AVn = AV100 x ((Dn - D0) / (D100 - D0)).

Specific embodiment
Hereinafter, with reference to the accompanying drawings of the aging meter of grease of the invention and the implementation method of grease Degree of Ageing evaluation method.
[summary of the structure of the aging meter of grease of the invention]
Fig. 1 is the block diagram of the structure for representing the aging meter of grease of the invention.
The aging meter of the grease is the dielectric constant for determining sample grease, and AV values (acid number) are calculated according to its measurement result
Device.
As shown in figure 1, the aging meter of the grease possesses as the CPU1 of control unit.CPU1 controls are surveyed as dielectric constant
The dielectric constant sensor 2 of order unit.Dielectric constant sensor 2 has and is immersed in comb electrodes in sample grease, by
Apply alternating voltage between the comb electrodes, the impedance of sample grease can be determined according to the change of frequency.According to the impedance
Measurement result, the dielectric constant of sample grease can be calculated.

In addition to AV values (acid number), additionally it is possible to be input into the instructions such as various numerical value, pattern selection to input unit 4.
Also, CPU1 is controlled as the memory 3 of memory cell.The storage of memory 3 is determined by dielectric constant sensor 2
Dielectric constant, AV values (acid number), other the various numerical value of input for going out.
Additionally, computing circuit 5 of the CPU1 controls as arithmetic element.Computing circuit 5 is carried out based on storage in memory 3
The computing of dielectric constant and AV values (acid number), other various computings.
Additionally, CPU1 is connected with liquid crystal display part 6.Liquid crystal display part 6 shows the AV being input into by the user of the device
The various information such as value (acid number), other various numerical value, the operation result based on computing circuit 5.
[grease Degree of Ageing evaluation method (action of the aging meter of grease) of the invention]
Fig. 2 is the chart of the relation between the dielectric constant and acid number (AV values) for representing grease.
(a) in Fig. 2 be represent the dielectric constant of the grease in fried shop (1), fried shop (2) and fried shop (3) with
The chart of the relation between acid number (AV values).

Additionally, in Fig. 2, transverse axis represents TPM values, the TPM values are the values related to the dielectric constant of grease.Therefore, the Fig. 2
Show the relation between the dielectric constant and acid number (AV values) of grease.
As shown in Fig. 2 the relation between the dielectric constant of grease and AV values is because of the water in food materials to be processed (Fried Fishes)
The conditions such as point content and it is different.That is, it is linear near when the relation between the dielectric constant to grease and AV values carries out linear approximation
It is different because shop is different like the slope of formula.It is thought that because the species of Fried Fishes, heat time have differences.For example,
In the case that fried amount and frequency are high fried shop as shown in (a) in Fig. 2, compared to its shown in (b) in Fig. 2
His shop, relative to the increase of dielectric constant, the increased ratio of AV values is big, the slope steepness of linear approximation formula.
Additionally, during grease is aging, not observed because of the increase of AV values with as described curve
Tendency, the experimental data in each shop can approximately be showed by straight line.When observation deviate from the point of straight line proximal line, make
AV values then have the error of ± 0.5 or ± 1.0 degree.As the main cause of error, it is believed that because by the color of grease come
Measurement accuracy, data are drawn again, the behaviour in service of grease is different etc..Even if considering these errors, it is also possible to pass through
Straight line approximately shows the increase of the AV values in the ageing process of grease.

That is, when the instruction that setting pattern starts is input into, CPU1 starts to perform setting pattern (setting work in step st1
Sequence), step st2 is proceeded to, if the acid number (AV of grease is not used0) it is 0, determine dielectric constant (D now0), and store (note
Record) in memory 3.
Then, step st3 is proceeded to, the grease in the replacing period (operating limit) under specific grease behaviour in service is determined
Dielectric constant (D100), together with acid number (AV now100) together storage (record) in memory 3.By acid-base titration etc.
Assay method asks for acid number (AV now100)。
Specific grease behaviour in service, refers to fried shop (1), fried shop (2), fried shop (3), tempura shop, Japanese meal
The behaviour in service of the grease in shop, butcher's and supermarket Deng Ge shops, it is believed that if then grease makes in identical shop
It is constant with situation.
Then, step st4 is proceeded to, when the instruction that mode determination starts is input into, CPU1 starts execution mode determination and (sets
Determine operation), step st5 is proceeded to, determine the dielectric constant (D of sample greasen), and by its measurement result (Dn) storage (record)
In memory 3.
Then, step st6, CPU1 are proceeded to according to the dielectric constant for storing (record) in memory 3 under setting pattern
(D0, D100) and acid number (AV100), by computing circuit 5 by following arithmetic expression, calculate the acid number (AV of sample greasen)。
AVn=AV100×{(Dn-D0)/(D100-D0)}
Then, the acid number that step st7, CPU1 show calculated sample grease by liquid crystal display part 6 is proceeded to
(AVn)。
[another example (1) of operation method]
In the aging meter of the grease, can be by the acid number (AV of the grease in the period of replacing100) it is defined as 100.In this case,
According to the dielectric constant (D of the sample grease for determiningn) acid number (AV of sample grease that calculatesn) represent until changing period
Untill percentage.
[another example (2) of operation method]
In the aging meter of the grease, can be by the unused state S of sample grease0With replacing period (operating limit) S100
In grease dielectric constant, i.e. S0Dielectric constant D0With S100Dielectric constant D100Between for example carry out 100 deciles, and set
Determine scale.Additionally, the numerical value for so carrying out decile can not be 100.
That is, it is such as following, it is defined as 1 degree：δD。
1 degree：δD=(D100-D0)/100。
If Degree of Ageing is defined as into An, then measured value D as follows according to dielectric constantnTo ask for Degree of Ageing An。
An=(Dn-D0)/δD。
Therefore, if Dn=D0, then An=0, if Dn=D100, then An=100.
